A resin composition, comprising:
- 100 parts by mass in total of a polypropylene resin (a) and a polyphenylene ether resin (b), and
- 1 to 20 parts by mass of a compatibilizer (c),
- wherein in the component (a),
- a proportion of a component having a molecular weight of 30,000 or less, which is determined by gel permeation chromatography (GPC, mobile phase:
- o-dichlorobenzene, standard substance:
- polystyrene), is from 3.0 to 5.1% of the entire component (a), and a proportion of a component having a molecular weight of 10,000,000 or more is from 1.0to 1.6% of the entire component (a).
A resin composition, comprising 100 parts by mass in total of a polypropylene resin (a) and a polyphenylene ether resin (b), 1 to 20 parts by mass of a compatibilizer (c), and 5 to 50 parts by mass of a filler (d),
- wherein in the component (a), a proportion of a component having a molecular weight of 30,000 or less, which is determined by gel permeation chromatography (GPC, mobile phase:
- o-dichlorobenzene, standard substance:
- polystyrene), is from 1.0 to 5.1% of the entire component (a), and a proportion of a component having a molecular weight of 10,000,000 or more is from 0.5 to 1.6% of the entire component (a).
